NSString)              .stringByAppendingPathComponent(dirName)          if !fileMan.fileExistsAtPath(cacheDir) {              fileMan.createDirectoryAtPath(                  cacheDir,                  withIntermediateDirectories: false,                  attributes: nil,                  error: nil)          }      }

  • Simple code like this: 
    var imgAddress = "http://blabla.com/blabla.png"      imgView.setImageCacheWithAddress(              imgAddress,              placeHolderImage: UIImage(named: "placeHolderImage")!,              cacheDirName: dirName)
